Silicon Anti-adhesive Sheet
The silicon component volatilized from silicone rubber will stubbornly adheres to the inner surface of the mask lens. It is a thing quite difficult to remove . To avoid this , we put the silicon anti-adhesion sheet on the inner surface of the mask lens at the time of manufacturing.
Because of the low coefficient of viscosity with this protection sheet, the sheet can be easily removed and also repeatedly reused. After the mask is used , wash and dry the mask, then put back the protection sheet on the inner surface of the maks lens. It minimizes the occurrence of fogging due to the volatilized silicon even after long-term storage.
